The equation d=rt is used to calculate distance, rate, or time, where d is the distance (in miles), r is the rate (in miles per
hour), and t is the time (in hours). Consider the statements below that describe the driving rates for three people. Graph the equation that represents the rate of the fastest person. Braylon drives at a rate of 50 miles per hour. Kiko drives for 9 hours and goes 405 miles. Presley drives 385 miles in 7 hours.
1 answer:
Answer:
Presley is the fastest
d= 55t
Step-by-step explanation:
d= rt
Divide by t
d/t =r
so we can find the rate
Braylon
50 miles per hour
Kiko
rate = distance/ time
= 405 miles / 9 hours
= 45 miles per hour
Presley
rate = distance/ time
= 385 miles/ 7 hours
= 55 miles per hour
Presley is the fastest
d =rt
d = 55 t
Remember t >=0 since it is time
